Oooh, another long one…. This one is interesting, I think.

Please be advised that this was written while I was panicked about floodwaters inundating my house, so it isn't perfect. Luckily, the river didn't break the levy walls, so I'm alright!

"Brennan, open up!" Booth said, growing impatient. He had been knocking on the door for at least ten minutes. When he still received no answer, he sighed, and pulled out his spare key.. He would have thought that Brennan would have demanded he return it when this all began, but she didn't.

The apartment was as neat as always, but something was off. There was a yellow envelope on the coffee table that hadn't been there when Booth stopped around just hours before. Cautiously, he bent down and tipped it over so the contents fell out. He was shocked by what was revealed.

Dozen's of photographs spilled out onto the table. There were red circles around people in all of them. When he bent down to get a closer look, Booth saw that many of the photographs had Parker in them, with a thick red circle drawn around him. Some of the photographs were of Brennan and him, and in all those photographs, there was a large, scratchy cross hastily drawn over Booths face, and in some there was a line between the partners.

As well as the photographs, several letters fell out. All were styled in the usual criminal fashion- letters cut out from newspapers and magazines glued down onto a blank sheet of paper. However, unlike most criminal notes, the criminal had taken great care to only use capitals when capitals where needed and had punctuation marks when they were called for. If Booth wasn't so worried, he would have marvelled at the articulation of the letter.

Stay away from Agent Booth, Dr Brennan, or I'll be forced to take action we will both regret. Parker Booth is seven, isn't he? Seeley would be so devastated if something were to happen.

'D'

Be careful, my dear doctor… I want your partnership ended. You've stayed away, but that isn't enough anymore. I hear you have a pair of young nieces…

'D'

Booth looked through the pictures again, and this time noticed that several had pictures of Hayley and Emma. Booth frowned, and flicked open his cell phone. He called in a team to secure the apartment, and called the squints in to gather what ever they could.

Picking up the envelope again, Booth noticed that it had 'evidence' stamped on the front. Brennan had clearly been compiling all the information she had on the mysterious 'D'. The action made Booth smile. It was something he would only expect from his partner.

A smaller, white envelope sat underneath the yellow one. Printed in Brennan's neat handwriting was Booth's name. He picked it up, and pulled out a letter.

Booth,

I know you've been blaming yourself for the end of our partnership. I tried to get you to blame me, but you could never do that. You would never accept that I have caused you pain.

The truth is, it was neither my fault, nor yours. It was 'D's. You must have found my evidence against him by now, so you must know who he is, and what he's done. I promised you I would look after Parker, Booth. It never once crossed my mind to not do as 'D' told me too once I realised that Parker was in danger.

There were times that I just wanted to come clean (I believe that's the saying) and tell you that someone was threatening me. I almost did. 'D' always knew. I just hope that Parker is safe now that you are reading this/

'D' will eventually come for me. I know that all this taunting me is only a preliminary step. Don't blame yourself, just find him, and make him pay. Please.

I am scared, Booth, but every time he calls, my resolve strengthens. Take care of the squints,

Bones.

There was a knock on the door as Booth finished reading. Walking over to answer it, Booth noticed his partners cell phone. He picked it up, and slipped it into his pocket.

The squints came inside at that moment, tired of waiting for Booth to answer the door. Angela was in tears, and the rest of them weren't much better. Booth pointed to the table and there were gasps of shock when it became apparent what had happened.

"This 'D' person must have kidnapped her!" Hodgins said. Booth nodded, and pulled out the phone.

"Angela, could you see if there are any recent calls from one number that seem suspicious to you? The number will be unfamiliar," He said, before rushing off to inform the team from the FBI on the situation.

At that moment, the cell began ringing. Alarmed, Ange called Booth, who waved at one of the tech's to get a trace on the number. Carefully, he opened the phone, and pressed accept.

"Agent Booth…" The voice on the other end said curiously. Booth clicked the speaker button so the entire room could hear. The squints huddled closer to him, and everyone was listening intently.

"Where is she?" Booth demanded. A sinister chuckle filled the room.

"Ah, just as direct as your dear partner. Well, your former partner," 'D' said. "She's still alive, don't worry. In a lot of pain, but alive. I'm not sure how long that will last, but she broke the rules."

"I swear, when I find you, you are going to regret this!" booth growled. There was a ping in the background, but luckily the phone didn't pick up the sound. "I want to talk to her."

"As you wish, Agent Booth. It's incredible. Even after everything that she did, you still care for the woman. Well, here she is."

"Booth? Booth?" Brennan's voice was heavy, and she was clearly in pain.

"I'm gonna get you out, Bones, I promise," Booth said. Brennan cried out in pain, and the squints winced, feeling the pain for her.

"Don't make promises you can't keep, Booth." She continued. "It's okay if you don't. Parker's safe now, Hayley and Emma are safe now. You're safe now. Bye, Booth."

"No! Bones! Bones?" Coughs rang out through the room, followed by a familiar laugh.

"Oh my, Agent Booth. It seems Dr Brennan was worse of than I thought. She's unconscious." 'D's taunting ended abruptly, replaced with the steady beeping of the dial tone.

"Tell me you got a trace on that!" Booth said, turning to the techs. One nodded.

"It's a pretty wide area, but you might be able to narrow it down." She said, passing a printout to the waiting agent. Booth thanked her.

"Hodgins, see if you can find a bug or something that can help me narrow this down. Angela, go through the letters, see if he says anything that could give him away. Cam, you… Go do something that will help, okay?"

Cam almost laughed at Booth's attempt to find her something to do. She nodded at the others before pulling out her phone.

"I'll call Max and Russ," She said.

"Don't mention the threats to Hayley or Emma, we don't want to worry them," Booth said in way of agreement. He just hoped that Brennan would be okay.

"As you wish, Agent Booth. It's incredible. Even after everything that she did, you still care for the woman. Well, here she is." The voice of her captor pulled Brennan into consciousness. He bent down to her level, and held out a phone. She turned her head, and the phone was placed beside her ear.

"Booth? Booth?" Brennan whispered, her throat dry and her body overcome by pain.

"I'm gonna get you out, Bones, I promise," Booth said. Brennan tried to sit up, but pain shot through her ribs and spine, forcing her to cry out. She lay back down carefully.

"Don't make promises you can't keep, Booth." She said. The darkness was clouding her vision and she knew she wouldn't remain awake much longer. Knowing the end was coming closer she tried to reassure her partner. "It's okay if you don't. Parker's safe now, Hayley and Emma are safe now. You're safe now. Bye, Booth."

"No! Bones! Bones?" Booth's voice was drowned out by coughs as Brennan slipped into unconsciousness once more. She was almost glad that the last thing she heard was her partner's voice…

Next chap. should be up later on today or early tomorrow. It'll have more from Bren's POV about her capture, and a bit of King of the Lab for Hodgy.

Ari.
